You could also make an analog EML circuit in theory, using electrical primitives that have been around since the 60s. You could build a simple EML evaluator on a breadboard. Things like trig functions would be hard to reproduce, but you could technically evaluate output in electrical realtime (the time it takes the electrical signal to travel though these 8-10 analog amplifier stages).
